Refresh of neighboring memory cells based on read status

An apparatus comprising:

• a memory array comprising at least one first memory cell;
• at least one sensor;
• and
• a controller configured to:
• read the first memory cell;
• determine a read status for the first memory cell;
• in response to determining the read status, refresh the first memory cell;
• determine errors associated with the first memory cell;
• collect sensor data from the at least one sensor;
• determine, based on the sensor data, at least one criterion;
• determine, based on the errors, whether the at least one criterion is satisfied;
• and
• in response to determining that the criterion is satisfied:
• determine a physical address of at least one second memory cell based on a physical address of the first memory cell;
• and
• apply a write refresh to the second memory cell.

A method comprising:

• reading first memory cells;
• determining a read status for the first memory cells;
• based on the read status, refreshing the first memory cells;
• determining respective physical addresses of second memory cells based on physical addresses of the first memory cells;
• determining errors associated with the first memory cells;
• and
• in response to determining that the errors exceed at least one threshold, applying a write refresh to the second memory cells.
